SELF-CLOSING SAFETY-PIN.

Be it known that I, JULIUS J. BRELL, a citizen of the United States of America, and resident of the city, county, :and State of New York, (whose post-office address is 530 West One Hundred and Fifty-ninth street, in said city,) have invented a new and useful Self-Closing Safety-Pin, of which the following is a specification. V

The object of my invention'is to improve the Construction of safety pins and devices of that class. v

The further and principal object of my invention is to provide a safety pin or device of that class which will at once be selfclosingand self-opening. To that end,-I have constructed the safety pin in two sections, the inserting point being on one section and the receiving guard on another section, both sections being pivoted or movably secured together, so that the resistance by the fabric into which the pin is inserted to the entrance of the pin will cause the sections to come together and bring about an 1 entry of the inserting point of onesection into the guard of the other section,thereby locking the sections together; and jconversely, upon applying force to one of the sections in the opposite direction and against the resistance of the fabric into which the pin has been inserted, the sections will be distended and the securing point and guard separated, so that the pin canbe readil removed. Both of these operations, bot

insertion and removal of the pin, can be performed in situations ordinarily inaccessible, and by the use of one hand, if necessary, u

My 1nvent1on 1s capable of being variously embodied, and it resides in the construction .and combination of parts hereinafter described and falling within the scope of the claims hereunto appended. 1

In the drawings forming part of: this specification, Figure 1 is a perspective view of a safety pin constructed in accordance with my invention, very muchenlarged, and in the closed condition; Fig. 2 is a side elevation of the same, the pin being shown in the open condition; Fig. 3 is a plan View of Fig. 1; and Fig. 4: is a sectional, elevationv on the line 1-1 of Fig. 2, lookingyin the direction of the arrows.

As previously stated, my invention may be variously embodied, but as the structure shown and described herein has been found,

inserted intothe fabric. grammatically indicated in Fig. 2 in dotted lines at .15

to give satisfactory results, I prefer that form, wlthout in any manner limiting my.-

. self thereto.

In the embodiment shown herein, the pin 1s made up of two sections a and b, pivoted to and movably controlled in relation to each other. The section a is what I call the guard section and b the pin section. The pm section comprises a rod 1, having a sharpened point 2 for insertion into the fabric,

or the. article to which the pin is to be applied, a conventional loop or turn 3 (which loop maybe omitted,.if desired) and a return bar 4 running substantially parallel withthe pin-bar 1, and which has formed at its outer end a guide loop 5, slightly upturned. The guard section a has a conventional form of guard 6 consisting of the shield 7, and the stop or detent 8,to which is secured a rod 9 which I will, for conveniences case, call the push rod. This rod'is tion'10,.which passes through the loop 5,

the flattening oeing had for the purpose of economizing lateral space and preventing turning between, the parts, and a loop 11 encircling a pin 12, which pin is secured to the pendent ears 13 of a guide 14:, surroundand.

moves-stifily through the loop 5, the sides of the loop bearing against the bar and tending to hold the parts inlocked position \when the pin is closed.

The operation of the pin is substantially as follows: The pointed'end of the 'bar is The fabric isdia- The guide 11 strikes the fabric and its resistance and the simultaneous movement. of the section 5 into the fabric motion of the the curved part 10 of the rod 9 to slide on the loop 5 and elevate the shield '7 oftlie with the pointed'end- 2 of the rod 1, the continuation of the move ment efiecting the complete and automatic closure of the pin as shown in Fig. 1. \Vhile in this position, the two points of contact of thesection with each other, that is, the section a, with the guide and the sections a Y provided with a flattened and curved por-' causes the guideto move in a direction oppin and cause and 6 through the loop, prevent any inadvertent movement of the parts and maintain the pin in a securely locked condition.

The detent or stop 8 may be omitted, as the, guide 14 and its other associated parts tend to prevent the inadvertent removal of the. pin point from the shield, although it may be retained, if desired. The operation of the parts is such that the insertion point of the rod 1 and the shield are automatically alined, so that all the operator has to do is to take hold of the pin at the loop end of section Z), and by inserting it and continu- -ing the operation, bring about complete penetration of the pin into the fabricand an automatic alinement of the inserting point with the locking shield 7. The removal of the pin from the article to which ithas been thus attached may be accomplished by reversing the afore-mentioned operation. By taking hold of the loop end of the section I), and merely pulling on it against the resistance of the fabric, which will bear against the guard portion of the section a,

.the section Z2 will be pulled out, the guide then moving toward the pin point of the rod 1, and gravity and the contact of the curved portion 10 of the rod 9 on the loop 5 will tend to force the guard section away from the fabric, freeing the insertion point 2 from the shield 7, and bring about the complete separation of the parts of the pin, as shown in Fig. 2, enabling it to be freely withdrawn from the fabric into which it was previously inserted.

It is manifest that my invention may be variously embodied without departing from its spirit; and I deem my invention to be as broad as the scope of the claims appended hereto.

I' claim: 7

1'. In an article of the class described, the

. combination with two sections, one carrying an inserting pin and a guide, the other carrying a guard. and being pivotally secured to the guide and slid'ably connected to the combination with a member having a guard and shield and a curved arm, a guide pivoted to said curved arm, and another section comprising an inserting pm on WhlCh said guide is movable and a loop on said pin section through which the guard section is adapted to be moved.

4 In an article of the class described, the combination of two sections, one comprising an inserting rod and a substantially parallel loop rod, a loop formed on the end of they latter, the other section comprising a rod with a guard and shield on one end adapted to be alinedwith the inserting rod, said guard and shield carrying rod passing through. the loop; of the first section, and movably engaging a guide movable on the inserting rod of the first mentioned section.

5. In an article of the class described, the combination of two. sections, one compris- -1ng an inserting rod and a substantially parallel extending rod having a loop at its end, the other section comprising a rod,
